Using a participatory action research framework to listen to Aboriginal and Torres Strait Islander people in Australia about pandemic influenza.
This article describes the use and effectiveness of the participatory action research (PAR) framework to better understand community members' perceptions and risks of pandemic influenza. In 2009, the H1N1 influenza pandemic affected Indigenous populations more than non-Indigenous populations in Oceania and the Americas. Higher prevalence of comorbidities (diabetes, obesity, asthma and chronic obstructive pulmonary disease) as well as pregnancy in Indigenous communities may have contributed to the higher risks of severe disease. Social disparity, institutionalised racism within health services and differences in access to culturally safe health services have also been reported as contributors to disadvantage and delayed appropriate treatment. ⋯ The most effective responses of this project were embedded in pre-existing relationships with individuals within organisations that had been established over a long period of time between Aboriginal medical services and investigators; however, research relationships established specifically for the purposes of the project were less successful because of changes in personnel and organisational support. The participatory approach used in this study has the potential to be applied to vulnerable populations in other countries.

Natural T Cell Mediated Protection Against Seasonal and Pandemic Influenza: Results of the Flu Watch Cohort Study.
A high proportion of influenza infections are asymptomatic. Animal and human challenge studies and observational studies suggest T cells protect against disease among those infected, but the impact of T-cell immunity at the population level is unknown. ⋯ Naturally occurring cross-protective T-cell immunity protects against symptomatic PCR-confirmed disease in those with evidence of infection and helps to explain why many infections do not cause symptoms. Vaccines stimulating T cells may provide important cross-protective immunity.
